Optimal subspace codes in ${\rm PG}(4,q)$
Published 27 Feb 2018 in math.CO, cs.IT, and math.IT | (1802.09793v1)
Abstract: We investigate subspace codes whose codewords are subspaces of ${\rm PG}(4,q)$ having non-constant dimension. In particular, examples of optimal mixed-dimension subspace codes are provided, showing that ${\cal A}_q(5,3) = 2(q3+1)$.
